Plug in chip tuning boxes

Our ET Box is designed to improve the performance of your car, by managing and adjusting your engine’s performance to suit your needs.

How does it work?

There are two main methods of tuning modern diesel and gasoline engines. One is by chip tuning or custom re-mapping, this involves using a special interface to read the program from the cars computer or ECU and then writing in a new program to increase performance. The second method is to use an external plug in tuning box, also known as a piggyback ECU or chip.

Our ET Box is a multi channel digital unit which connects into the existing wiring of the vehicle using original manufacturer’s connectors. A control unit is then attached which can override the signals coming from the engines sensors to the car’s ECU. This unit alter the signals to allow the injectors or common rail to inject the optimum amount of fuel at the required times, while simultaneously adjusting turbo pressure to keep the air/fuel ratio correct. Camshaft timing and inlet temperatures are also monitored to produce the best and safest result for your vehicle.

Why should I choose the ET Box over others that are on the market?

Choosing the wrong box can cause serious damage to your engine, leaving you out of pocket hundreds or even thousands of dollars.

Our ET Box is unique compared to most others on the market because we use multi channel technology monitored with multi plug inputs (OEM grade). This enables us to monitor more of your engine’s parameters for the best performance increase while most importantly remaining safe.

The advantage of this is most noticeable on newer cars from the last couple of decades, especially diesels fitted with a DPF (Diesel Particulate Filter). The DPF collects carbon/soot and is designed to capture most of the polluting carbon coming from your engine while you drive on short town journeys. Then when you use the highway at a maintained speed, the vehicle’s ECU (computer) puts the DPF in to regenerate mode and uses extra fuel to superheat and dispose of the carbon away from the populated areas. Where problems arise is if you tune these engines just by increasing fuelling as you would have on older diesels, this creates more carbon/soot and the DPF can become blocked. If the dealer can’t manually re-generate the DPF you may need to replace it which can get costly.

The ET Box also helps increase turbo pressure by adding more air with the optimal amount of fuel, this will greatly reduce the diesel particulate filter (DPF) from becoming blocked and the car will also have more power compared to one tuned to simply add fuel. Viridian Performance can guarantee that our ET Boxes are of the highest standard available, most boxes carry the highly regarded German T.U.V certification/approval and are rigorously tested and guaranteed for 2 years. Most of our boxes can also be adjusted to nine different power settings by the user depending on the level of power required, if appropriate.

Could the ET Box damage my engine?

Our boxes are specifically designed to run within the manufacturer’s safety limits and tolerances, the extra performance runs within the tolerance of the engine and gearbox. The service intervals of the vehicle will not change, however it’s important that they be done on time using original manufacturer’s parts.

It’s also important to regularly check the engine oil level and top up if necessary with the correct oil as most modern engines are designed to use some oil to increase the lifespan of the engine.

Tuning box Vs custom ECU flash tuning

While we offer both kinds of tuning options, both tuning box and custom ECU flash tuning have their pros and cons.

Custom flash/chip tuning:

Active and mostly permanent overwriting of the manufacturer’s software.

Manufacturer safety protection programs often modified or disabled.

Tuning usually exceeds the load limits of the engine.

Elaborate installation at the tuner only with special tools.

Can be fully customised but is usually a time consuming and costly procedure.

Viridian Performance ET Box:

Optimisation of the manufacturer’s software without overwriting it.

All engine safety protection programs are retained.

Tuning only within the load limits of the engine.

Easy self-installation without special tools in as little as 10 minutes.

Easy, fast and 100% recoverable.

Less vehicle down time and less potential damage to the factory ECU and components.

Significantly less cost compared to custom tuning. (Pricing is about 50% less with very close to the same end results in most circumstances).
